free download
AbstractAs part of a multi-channel, multi-band evaluation platform for future wireless sensor network applications, an IEEE 802.15. 4a standard conform transmitter is investigated. The paper gives an overview of our transmitter concept and ultra-wide band

Wideband Transmitter with Poly-phase Harmonic Cancellation Method
free download
ABSTRACT This paper demonstrates 8-path 8-phase harmonic cancellation using two IQ modulators. The poly-phase multi-path technique requires two phase shifters. In the transmitter, a second high frequency wide band phase shifter can be implemented with a

Abstract: UHF spectrum is used world-wide for land mobile radio systems for commercial, industrial, public safety, and military purposes. Therefore, the studying of UHF transmitter systems is pressing need. A critical element of any transmitter is the frequency synthesizer

A Pulsed-Based, Ultra- Wideband Transmitter
free download
This research focused on an ultra-wideband (UWB) transmitter fabricated in a 0.18- m SiGe BiCMOS process that uses a tanhshaping technique to generate approximate Gaussian pulses in the 3.1-10.6-GHz band. The MIT UWB architecture uses pulse-based, binary

Intra/Inter Chip Wireless Interconnect System for ULSI (2)-A CMOS Ultra Wideband Transmitter
